To recap, I met Mansa Musa and built some wonders. I used the Great Wall to teleport a barb Archer toward Musa; the barb pillaged Musa's wheat and horse. My wonders so far are the Great Wall (T68), Pyramids (T71), Hanging Gardens (T96). I have 7 cities; Musa has 3.
It is 200 BC T107 and Musa now has Alphabet, so we can begin to trade techs. Musa
wants Mathematics;
can research Meditation, Monotheism, Monarchy, Aesthetics, Currency, Horseback Riding, Metal Casting, Compass;
will trade Polytheism, Sailing, Alphabet. Those are the only techs in my foreign advisor screen, but I deduce that Musa also knows Priesthood and Code of Laws (because he founded Confucianism and adopted Caste System). Musa's economy is about the same size as my economy (going by the GNP graph), but Musa is more advanced than me.
I wait 3 turns to finish Currency before I trade techs. I get Currency and Musa gets Monotheism in 125 BC T110. On the same turn, Musa opens the trade table to offer his Polytheism + 130 gold for my Mathematics. I want Sailing. I negotiate and accept his Polytheism + Sailing + 20 gold for my Math. With Sailing, I begin my national Moai Statues in Green Water. I also sell my spare corn to Musa for 1 gold per turn. I begin researching Aesthetics at 20% science. 1 turn later, I get Mansa's Code of Laws for my Sailing, and begin Chichen Itza in Iris's Rainbow. I also settle my 8th city.
The new city is
Ocean of Heaven (8th, 100 BC T111, with fish, whale, silver in 2nd ring). I also need to settle the northeastern "X" tile, because if I don't, then Musa might settle and steal the silver or marble in his 1st ring. T111, when I settle of Ocean of Heaven, is also when I connect the marble. T111 is also when I get wheat.
My culture steals the wheat from Musa! This is the only wheat on our continent; Musa loses the wheat again soon after he reconnected it (after the teleported barb pillaged it). I am surprised that one of my cities reaches the wheat tile. My Aither Desert has 2nd-ring borders and can't reach the wheat. My capital Fertile Land has 4th-ring borders, so the wheat must be in the 4th ring. (I would have guessed 5th ring.) A new city might fit on the "X", 2 tiles north of the wheat, but I don't want to settle so close to Musa's border.
In 50 AD T117, my northeastern "X" becomes
Mercuria (9th city, so Musa can't settle and steal the silver or marble). Each of Ocean of Heaven and Mercuria need some culture to expand borders to reach a fish in the 2nd ring. I can't spread religion, so I build Monuments for culture. Mercuria steals the marble from Demeter Forest, and Ocean of Heaven will get a forest chop. If I can get 2 forest chops, I would build a Library, not a Monument; but each city has only 1 forest. (I did build a Library with 2 forest chops in Demeter Forest, my only city to get a Library before a Granary. That Library did annex the marble.)
I want more wonders for a Cultural Victory. There are 2 big groups of wonders: the 1st group at Aesthetics to Music in the tech tree, and the 2nd group at Electricity to Mass Media. In my 11th regular game, I played as Tokugawa of Japan, built most of the 1st group, but lost the 2nd group to Elizabeth of England. I raced Elizabeth to a Cultural Victory. I'm not sure, but Elizabeth might have won 2 turns before me! We aborted the race, because Elizabeth built the United Nations, where I luckily grabbed a Diplomatic Victory. In this Augustus game, I approach the 1st group of wonders. I will skip the Statue of Zeus (missing ivory) and Shwedagon Paya (missing gold), but I want (from least to most) the Parthenon, the Great Library, and the Sistine Chapel.
Musa learns Aesthetics in T117, a turn before I learn it in T118. I switch Green Water from the Moai Statues to the Parthenon. Musa turns away from Music and begins Horseback Riding, while I begin Literature to (Great Library). I need a Library before the Great Library, but Fertile Land would finish its Library 2 turns after I get Literature; so I whip the slaves and hurry the Library in T118, then produce Wealth until 175 AD T122, when I begin the Great Library (which gets most of my forest chops).
I finish the
Great Library (250 AD T125, Fertile Land), then the
Parthenon (300 AD T127, Green Water). I am 1st to Music (400 AD T131) and finish the
Sistine Chapel (425 AD T312, Fertile Land). I had accumulated 2 Great Engineers by having both the Pyramids and the Hanging Gardens in Fertile Land. I used the 1st Great Engineer to hurry the Sistine Chapel, and will save the 2nd Great Engineer for another wonder. My 3rd great person is the free Great Artist from Music, whom I settle in Iris's Rainbow.
I trade Music to Musa to get gold, Priesthood, and Monotheism (Organized Religion). After I have the Sistine Chapel, I take 2 turns of anarchy to convert to Confucianism and adopt Organized Religion. (I refuse to adopt Caste System, but stay in Slavery to whip more wonders.) I have Confucianism in 4 of my 9 cities. I finish my national Moai Statues (540 AD T137, Green Water) and finally
Chichen Itza (560 AD T138, Iris's Rainbow). I was slow to build Chichen Itza, because it got no forest chops.
Someone had founded Christianity, but I try for the last 2 religions. I research Meditation, then Philosophy and found
Taoism (600 AD T140, Vulcan). I research Theology, trade it to Musa to get Monarchy, then research Divine Right and found
Islam (940 AD T157, Mercuria).
In 820 AD T151, "Machiavelli has completed his greatest work, The Most Powerful Civilizations in the World!" Among 7 civs, Musa is 6th and I am 7th (last). Musa has Horse Archers and Longbowmen. I only have a few Archers, a Chariot, and a bunch of worthless Warriors. I can make Spearmen to defend against Horse Archers, but I can't make any medieval army units. (I forget about my unique unit, the Praetorian.) I continue to ignore war techs as I run through Paper and Education to Liberalism.
I complete
Angkor Wat (1040 AD T164, Iris's Rainbow), the
Spiral Minaret (1110 AD T171, Fertile Land), and the
University of Sankore (1170 AD T177, Green Water). In 1440 AD T174, Musa offers his Calendar for my Philosophy; I agree to give Philosophy (because I have Angkor Wat), but negotiate and take Metal Casting (plus World Map), not Calendar. I use Metal Casting to add Forges to my cities. I take 253 gold for failing the Hagia Sophia (as I expect; I was late to Theocracy) as I approach Liberalism.
In 1220 AD T182,
"Your Civilization is the first to discover Liberalism! Choose a free technology..."
These choices are bad! I want Nationalism, but I forgot that I need Civil Service for Nationalism. My choices are Feudalism, Civil Service, Drama, Alphabet, Calendar, Horseback Riding, Compass, Construction, Machinery, Gunpowder. Musa already know most of these; he only misses Compass and Gunpowder. I choose Gunpowder, because it costs the most beakers, and because Musketmen can defend my cities better than Archers. I trade Gunpowder to get Musa's Civil Service (plus Drama, map, 50 gold). I later give Divine Right (plus 25 gold) to get Musa's Machinery and Alphabet, so I can research Printing Press after Nationalism.
Mansa Musa completes his 1st wonder, the Apostolic Palace; I'm so happy that I vote in 1360 AD T196 to give the AP residency to Musa. (The other civs with Theology might have missed the AP by wasting their hammers on Hagia Sophia.) I complete Versailles (1370 AD T197) and the Taj Mahal (1380 AD T198). I enter my 1st golden age and will change civics.
In demographics, I rank 4th in food (172 million bushels; rival best 418, average 207, worst 73). This is dangerously low. My civ might be too small to win by space or via the United Nations. I would need to either get my Cultural Victory, or go to war to stop someone else's victory. I rank 2nd in land, and might get more food after I settle my 3 coastal "X" spots; it would raise my city count from 9 to 12 and add 1 fish. Musa never sent a Settler east, is stuck at 3 cities.
I know almost nothing about the civs on the other continents. I almost never check the list of top 5 cities, but this list is most useful now.
The 1st city, size 13, stands out because it has the most holy shrines of Judaism, Hinduism, and Buddhism. It also has Stonehenge and the Statue of Zeus. The guy (or gal) who leads this civ probably started with Mysticism, got his capital stuck on Stonehenge, and founded all 3 early religions in his capital, before he had a 2nd city.
The 2nd city, size 16, has most of the game's other wonders: the Great Lighthouse, the Colossus, the Oracle, Hagia Sophia, the Mausoleum of Mausolos, Shwedagon Paya. This guy (or gal) might have lost the race to Buddhism, then learned Priesthood (Oracle) and took the Oracle's free tech, Metal Casting (Colossus). I guess that Oracle Guy might have founded Christianity. Because both cities were founded in 4000 BC, I am sure that Shrine Guy and Oracle Guy are from different civs.
I have my Fertile Land at 3rd and Iris's Rainbow at 4th, then Musa has Timbuktu with his Apostolic Palace at 5th. The only wonders that I can't find are the Temple of Artemis and Notre Dame. I don't know, but I suspect that Oracle Guy has Notre Dame, and someone else has Artemis. If Oracle Guy reaches Electricity, he might race me for the Cultural Victory. I am aiming for Democracy and the Statue of Liberty, but after that, I want to get Optics and find the civs on the other continents. Or they might find me?
